[gdal-dev] How to locate where the raster min and max values are?

would be happy with the first pixel at the moment.

I've submitted a processing tool for QGIS 3.42 to do this here:
https://github.com/qgis/QGIS/pull/59332 . This uses Even's new GDAL api so
should be super-efficient & fast to calculate. 🥳

Thanks for raising this interesting discussion, a lot of nice things have
come out of this!
